Ukuqonda uMngcipheko wokuqhushumba kweebhetri ze-Polymer Lithium-Ion

Ngokusekwe kuhlobo lwe-electrolyte esetyenzisiweyo, iibhetri ze-lithium-ion zihlelwa kwiibhetri ze-lithium-ion (LIB) kunye neebhetri ze-lithium-ion ze-polymer (PLB), ezaziwa ngokuba ziibhetri ze-lithium-ion zeplastiki.

Ii-PLB zisebenzisa i-anode efanayo kunye nezinto ze-cathode njengeebhetri ze-lithium-ion zamanzi, kuquka i-lithium cobalt oxide, i-lithium manganese oxide, izinto ze-ternary, kunye ne-lithium iron phosphate ye-cathode, kunye negraphite ye-anode. Umahluko ophambili ulele kwi-electrolyte esetyenziswayo: ii-PLBs zithatha indawo ye-electrolyte engamanzi nge-polymer electrolyte eqinileyo, enokuthi "yomileyo" okanye "njengejeli." Uninzi lweePLB okwangoku zisebenzisa i-polymer gel electrolyte.

Ngoku, umbuzo uvela: ngaba iibhetri ze-lithium-ion ze-polymer ziqhuma ngokwenene? Ngenxa yobungakanani babo obuncinci kunye nobunzima obulula, ii-PLBs zisetyenziswa kakhulu kwiilaptops, ii-smartphones, kunye nezinye izinto zombane eziphathwayo. Ngezi zixhobo zihlala ziqhutyelwa ngeenxa zonke, ukhuseleko lwazo lubaluleke kakhulu. Ngoko ke, ukhuseleko lwe-PLB lunokuthenjwa kangakanani, kwaye lubeka ingozi yokuqhuma?

1. Ii-PLB zisebenzisa i-electrolyte efana ne-gel, eyahlukileyo kwi-electrolyte engamanzi kwiibhetri ze-lithium-ion. Le electrolyte efana nejeli ayibilisi okanye ivelise izixa ezikhulu zerhasi, ngaloo ndlela iphelisa uqhushumbo olunobundlobongela obunokwenzeka.
2. Iibhetri ze-lithium zihlala zihamba nebhodi yokukhusela kunye nomgca wokuchasana nokuqhuma ukukhusela. Nangona kunjalo, ukusebenza kwabo kunokulinganiselwa kwiimeko ezininzi.
3. Ii-PLB zisebenzisa i-aluminium yeplastiki yokupakisha eguquguqukayo, ngokuchasene ne-casing yentsimbi yeeseli zamanzi. Kwimeko yokhuseleko, badla ngokudumba kunokuba bagqabhuke.
4. I-PVDF, njengesixhobo sesikhokelo see-PLBs, iqhuba kakuhle kakhulu.

ImiGaqo yoKhuseleko yee-PLBs:

• Isekethe emfutshane: Ibangelwa zizinto zangaphakathi okanye zangaphandle, rhoqo ngexesha lokutshaja. Ukungadibani kakuhle phakathi kweepleyiti zebhetri nako kunokukhokelela kwiisekethe ezimfutshane. Nangona ezininzi iibhetri ze-lithium-ion ziza kunye neesekethe ezikhuselayo kunye nemigca yokuchasana nokuqhuma, oku akunakusoloko kusebenza.
• Ukugqithisa: Ukuba i-PLB ihlawuliswe nge-voltage ephezulu kakhulu ixesha elide, inokubangela ukushisa kwangaphakathi kunye nokwakhiwa koxinzelelo, okukhokelela ekwandiseni kunye nokugqabhuka. Ukutshaja ngokugqithiseleyo kunye nokukhupha ubunzulu kungonakalisa ngokungenakulungiseka ukumila kweekhemikhali zebhetri, okuchaphazela kakhulu ubomi bayo.

I-lithium iyasebenza kakhulu kwaye inokubamba umlilo ngokulula. Ngexesha lokutshaja kunye nokukhutshwa, ukufudumeza okuqhubekayo kwebhetri kunye nokwandiswa kweegesi eziveliswayo kunokunyusa uxinzelelo lwangaphakathi. Ukuba i-casing yonakele, inokukhokelela ekuvuzeni, umlilo, okanye ukuqhuma. Nangona kunjalo, ii-PLBs kunokwenzeka ukuba zidumbe kunokuqhuma.

Izinto eziluncedo kwii-PLBs:

1. Umbane osebenzayo ophezulu ngeseli nganye.
2. Ubuninzi bomthamo omkhulu.
3. Ukuzikhupha okuncinci.
4. Ubomi bomjikelo omde, ngaphezulu kwemijikelo engama-500.
5. Akukho mpembelelo yenkumbulo.
6. Ukusebenza kakuhle kokhuseleko, usebenzisa i-aluminium yeplastiki yokupakisha eguquguqukayo.
7. Icwecwe kakhulu, inokungena kwiindawo ezilingana nekhadi letyala.
8. Khaphukhaphu: Akukho mfuneko yecasing yentsimbi.
9. Umthamo omkhulu xa kuthelekiswa neebhetri ze-lithium ezilinganayo.
10. Ukuchasana okuphantsi kwangaphakathi.
11. Iimpawu zokukhupha ezigqwesileyo.
12. Uyilo lwebhodi yokhuseleko olulula.

Izinto ezingeloncedo kwii-PLBs:

1. Iindleko eziphezulu zemveliso.
2. Isidingo sesekethe yokukhusela.
